Rose UKCA suites on MONsooN

This page describes the Rose suites with UKCA that are installed on MONsooN.

Disclaimer: The main purpose of these suites is for model development and overall assessment of performance. Until the suites are assessed properly and released via the UKCA Release Jobs page, they should be considered as not suitable for Science applications.

Pre-requisites

For the initial Rose setup and instructions on using Rose on MONSooN, see this page (requires Collaboration Twiki login).

UM10.2

puma-aa237: This is an UKCA StratTrop/CheST Chemistry +GLOMAP suite at N96L85 resolution. The suite is derived from the UM Global Atmosphere development suite mi-ah615, but using the StraTrop or CheST scheme instead of Offline oxidants.
The suite is set up to archive model output (to the MASS tape drive) and submit the next segment, so it can be used for performing long simulations.

UM10.3

puma-aa262: This is a test suite based on the UKCA configurations in the UM trunk and can simultaneously run the following configurations at N96L85:

StratTrop(CheST)+GLOMAP+RADAER+Activate

Offline oxidants+GLOMAP+RADAER+Activate with two PE configurations

Both the configurations carry out a 2-day simulation that requires between 10 - 15 minutes to complete on the Cray. The CheST Configuration uses 16x8 PEs, while the Offline configuration uses 16x8 and 8x12 PEs.

UM10.4 (Test Suite)

puma-aa322: This is a test suite based on the UKCA configurations in the UM trunk and can simultaneously run the following configurations at N96L85:

StratTrop(CheST)+GLOMAP+RADAER+Activate

Offline oxidants+GLOMAP+RADAER+Activate

The Offline oxidants job includes tests to compare between 16x8 vs 8x12 PE configurations (TEST_PE), as well as between runs composed of different segments (NRUN-CRUN, CRUN_TEST)
The main configurations carry out a 2-day simulation that requires between 10 - 15 minutes to complete on the Cray.
A significant change from the UM10.3 suite is that all the tasks are run from the same base app (um), making use of optional configurations : ROSE_APP_OPT_CONF_KEYS in the suite.rc.

UM10.5 (Test Suite)

puma-aa358: This is a simple upgrade from the UM10.4 suite a test suite continues to run the following configurations at N96L85:

StratTrop(CheST)+GLOMAP+RADAER+Activate

Offline oxidants+GLOMAP+RADAER+Activate

AS for UM10.4, the Offline oxidants job includes bit-reproducibility between 16x8 vs 8x12 PEs (TEST_PE) as well as the NRUN vs CRUN, CRUN_TEST)
The main configurations carry out a 2-day simulation that requires between 10 - 15 minutes to complete on the Cray.

UM10.6 (Test Suite)

MONSooN: puma-aa405MetO: mi-ap240
This is an upgrade from the UM10.5 suite a test suite continues to run the following configurations at N96L85:

StratTrop(CheST)+GLOMAP+RADAER+Activate

Offline oxidants+GLOMAP+RADAER+Activate

The Offline oxidants job includes bit-reproducibility between 16x8 vs 8x12 PEs (TEST_PE), while the Strat+trop job includes a NRUN vs NRUN+CRUN (CRUN_TEST)
The main configurations carry out a 2-day simulation that requires between 10 - 15 minutes to complete on the Cray.

UM10.7 (Test Suite)

MONSooN: puma-aa428MetO: mi-ar330
This is an upgrade from the UM10.6 suite a test suite continues to run the following configurations at N96L85:

StratTrop(CheST)+GLOMAP+RADAER+Activate

Offline oxidants+GLOMAP+RADAER+Activate

The Offline oxidants job includes bit-reproducibility between 16x8 vs 8x12 PEs (TEST_PE), while the Strat+trop job includes a NRUN vs NRUN+CRUN (CRUN_TEST)
The main configurations carry out a 2-day simulation that requires between 10 - 15 minutes to complete on the Cray.

UM10.8 (Test Suite)

MONSooN: puma-aa438MetO: mi-at557
This is an upgrade from previous versions of the suite and continues to run the following configurations at N96L85:

StratTrop(CheST)+GLOMAP+RADAER+Activate

Offline oxidants+GLOMAP+RADAER+Activate

The Offline oxidants job includes bit-reproducibility between 16x8 vs 8x12 PEs (TEST_PE), while the Strat+trop job includes a NRUN vs NRUN+CRUN (CRUN_TEST)
The main configurations carry out a 2-day simulation that requires between 10 - 15 minutes to complete on the Cray.
